About This Calendar Page
This 2025年12月 calendar page is built for search visibility and day-to-day usefulness. It combines a clean Sunday-to-Saturday grid, readable date hierarchy, live local time in the control bar, and route-based navigation so each month and yearly view can stand on its own.
The holiday layer uses country-aware data and can already power pages like /calendar/us/2026/april. The underlying day model also keeps a reserved moon phase field so we can extend the page with richer astronomical details later without changing the route structure.
